I have my NS2 rooted, and have modified some configurations (mainly FTP settings as I need to prevent access to the open share via FTP), it works perfectly, but if I ever need to restart the NS2 all the settings are set back to default, meaning I have to login and change all my settings again after every restart.

Do you know where I can find these default settings so I can change them to what I need, or that I can prevent this reset happening each re-boot?
